Apparatus for converting rotational movement into reciprocating lifting movement
First Claim
1. An apparatus for converting rotational omvement into reciprocating lifting movement or vice versa, comprising a bearing body having a first cylindical wall section with first guide grooves that extend in the direction of a lifting movement;
- a rotary element supported on said bearing body so as to be ablet o rotate and having a second cylindrical wall section with second guide grooves that are arranged at an angle to said first guide grooves;
a lifting element that is supported on said bearing body so as to move back and forth and having a third wall section that protrudes between said first and said second wall sections;
continuous bearing drillings provided in said third wall section and having axes that are transverse to the lifting movement;
a force transfer system with driver balls that are guided within said bearing drillings and supported in part in said first and second guide grooves;
two driver balls lying in each of said bearing drillings one behind the other in an axial direction and resting against each other, one of said driver balls being supported in part in said first guide groove and the other of said drive balls being supported in part in said second guide groove.

Abstract
An apparatus for converting rotational movement into reciprocating lifting movement or vice versa, compriss a bearing body that incorporates a first, cylindrical wall section with first guide grooves, a rotary element that is supported on the bearing body so as to be able to rotate and that incorporates a second cylindrical wall section with second guide grooves that are arranged at an angle to the first guide grooves, a lifting element that is supported on the bearing body so as to move back and forth and that incorporates a third wall section, in which continuous bearing drillings with axes that are transverse to the lifting movement are arranged, and a force transfer system with driver balls that are guided within the bearing drillings. In each bearing drilling there are two driver balls that lie one behind the other in the axial direction and which rest against each other. One such driver ball is supported in part in the first guide groove and the other is supported in part in the second guide groove.
